ELECTROCONDUCTIVE ADHESIVE

摘要

The inventive electroconductive adhesive comprises a resinous matrix, as a dispersing medium of conductive particles, of a polyester-based urethane resin admixed with a masked isocyanate compound as the curing agent. By virtue of the masking of the isocyanate reactivity of the curing agent, the adhesive composition is stable during prolonged storage under a hot temperature or high-humidity condition but can exhibit curing activity when the adhesive is heated at a temperature at which the isocyanate reactivity can be restored.
